New help with adjustable timing chain SB - 07/21/10 03:49 PM
410 Stroker with Comp Cam XR286HR,
My ENgine builder is no longer in business for personnal reasons but he was really reliable.
In my documentation & verbally he told me that he has installed the Cam with 2 degree advance (104 instead of 106). This was to have good torque at low RPM since my gear was only 3:55.
I am now installing a 3:91 and would like to put the Cam back were the manufacturer recommend (I have also used dyno software to validate).
I trust my former engine builder but the crank gear is installed with the keyway labeled 0 degree??? Is this possible? When I lower the Cam gear dot down at 6 o'clock it is lining-up with the outboard 0 degree mark on the crank gear (marks closer to the chain).
My question is, is it possible that my Cam was installed with 2 degree advance even if the crank gear is in the 0 degree keyway? (JP Performance billet timing set)?
Thanks, will try to post picture later.
